Do you mean on standby or actively pumping? In most cases these are controlled by a pressure valve with no current flowing unless a tap is opened. When running it'll consume whatever power it's rated at.Can I ask - slighty different topic if ok - does anyone know whether these water pumps, being switched on 24/7, are hard on electricity?
We have a Stuart Turner Monsoon in the hot press beside the kids room, never wakes them. Sits on one of these anti-vibration pads and connects via flexi-hoses with a little play.anyone found a less noisy pump
